Well, back on topic. I got home with the lathe / mill today. I'm
delighted to report that it was sitting on a little rubbermaid 5
drawer tool box that contained a treasure trove of goodies. We
haven't inventoried everything yet but there's a lot of stuff. The
lady who was assigned to escort me was the very same person who used
the lathe before the plant closure. It was like she was giving up her
baby to an orphanage. Plant closures are so gut wrenching.

While I was gone the VFD came for the KBC mill. So the family machine
shop seems to be coming together quickly. I'm reviewing the technical
instructions on the inverter. There is mention of some additional
components such as a "reactor" in case the input power is out of
balance by more than 3% plus a radio noise suppressor. The latter
probably isn't needed. But I think the "reactor" may apply to us.
Since we're in a rural location power is pretty dicey. In fact,
recently, one leg of the 220v supply died completely. I don't know
what that would do to an inverter. But at $350 a pop I don't wanna
find out. Even with my poor math one leg is a tad over 3% if I'm not
mistaken.

I dug out my 1941 Machinist's Handbook this evening. I hope we can
find somebody to teach us the proper care and feeding of the lathe
before January. That's when the next junior college manual lathe
operator's course meets.

Thanks to everybody for your support. This is a superb group.

Unless your VFD is very unusual, it was designed to run on 3 phase
power, but will run on single phase with some derating. You're
planning on connecting it to single phase, which means one of the
VFD's power inputs will be unconnected -- a 100% imbalance -- and a
reactor isn't going to help that situation.

I've purchased line reactors from these folks, you may find useful
information in their technical articles.

Ned,

Thanks for the clarification. I'm doing mortal battle with my own
ineptitude at things electrical.

Good for you!! that probably will double the value of the machine.
If you don't have the full set of manuals and repair guides, email me
and I'll send them.

Well, "baby" went to a good home. I'm sure there were tears shed and
promises to keep in touch ;)

Very good. Wish there was one around here.
